Field Intelligent Device – Premium Value Series
Electromagnetic Flowmeter
Introduction
The electromagnetic flowmeter uses Faraday’s Law of
electromagnetic induction to measure the process flow.
The device consists of two units: a detector, through
which the fluid to be measured flows and in which
low-level signals proportional to flow rates are
obtained; and a converter, which supplies excitation
current to the detector, and amplifies the signals from
the detector and then processes and converts the signals
into the 4–20mAdc current signal or communication
signal. Combined with a multi-functional converter
LF620 (combined type) or LF622 (separate type)
equipped with its original patented noise-suppression
circuit and advanced algorithms. The GF630 has a very
high tolerance to noise, giving the unit a very stable
output even for slurry fluid measurement. IR (Infrared)
switches enable the parameter setting of the converter
without removing the cover. Flow direction can be set
in either way, and its unique 128 x 128 dot matrix LCD
display allows the LCD to be rotated electronically to
90, 180 and 270 degrees without opening the cover.
The terminal block in LCD side make easy to wire in
case of the combined type.
The AF900 hand-held terminal (HART*1
communicator) can be used to communicate with the
flowmeter from a remote place. PROFIBUS-PA*2 or
Modbus*3 interface is available as an option.

Overall Specifications
*2: PROFIBUS is the communication protocol for factory and process automation that
the PROFIBUS Organization recommends. Instead of analog control with a
conventional analog signal (4-20mA), it is fieldbus which digitizes all signals.
Flowmeters support PROFIBUS-PA.
*3:Modbus is the communication protocol that Modicon Inc. developed. Physical
layer is RS485.
Measurement range in terms of flow velocity:
0 – 0.3 m/s to 0 –10 m/s (0 –1.0 ft/s to 0 – 32.8 ft/s).
0 – 0.1 m/s to 0 – 0.3 m/s (0 – 0.3 ft/s to 0 – 1.0 ft/s)
range is available optionally for meter size 1/2” to
18” (15 to 450 mm).

Wiring Precautions (PROFIBUS or Modbus)
(1) For wiring path, avoid places near electrical
equipment that may cause electromagnetic
induction or electrostatic induction interference
(such as a motor, transformer and wireless
transmitter).
(2) Use a PROFIBUS-PA cable or a RS485
twist-pair cable for signal cable. In addition,
make sure to use a shielded cable to improve
noise resistance. Furthermore, installation of
signal cable in metal conduit is recommended.
(3) General cables are designed for indoor use where
cables are not exposed to humidity, rain, etc.
When you install cables, make sure to check the
operating conditions such as the operating
temperature range of the cable by contacting its
manufacturer.
(4) When you carry out cable end treatment of cable,
use a dedicated cable stripper etc. so that the core
wire of the cable will not be nicked or damaged.
In addition, for cables, be careful of allowable
maximum bend diameter etc. (Basically, do not
install cables in a way cables are twisted or
bent.).
(5) Consider installing a PROFIBUS-PA arrester in
the communication path of PROFBUS-PA so
that the electromagnetic flowmeter will not be
affected by lightning etc.
(6) The electromagnetic flowmeter is not equipped
with terminating resistors.Use the terminating
resistor unit for PROFIBUS-PA or junction box,
if necessary.
10
(7) Only one PROFIBUS-PA cable goes through a
cable gland of the Electromagnetic Flowmeter.
Use the junction box at system configuration.
(8) Install a terminator to flowmeter that connected
to end of Modbus network.
Allowable cable length (m)
Wiring Precautions
(1) Explosion proof type flowmeters are not
provided cable glands.
Refer to the part Cable connection port at
detector and converter.
(2) Connect the grounding wire (IV wire 5.5mm² or
more) to a good earth ground (100 or less
ground resistance). Make the wire as short as
possible. Do not use a common ground shared
with other equipment where earth current may
flow. An independent earth ground is
recommended.
(3) The allowable cable lengths between the
detector and converter for the separate type
flowmeter depend on the electrical conductivity
of the object fluid. See Figure 8.
(4) DO1, DO2, and DI use the same common
terminal (COM). This COM can not connect to
other equipments which have their own ground
terminal. (Power supply for connecting to DI or
DO, etc…) Need to wire separately.

Meter Size
To select the meter size:
See Table 2 to 3 and find meter sizes within the
velocity of 0.1 to 10m/s for a specified full-scale
(measuring range high limit) flow. Select one that
has its full-scale velocity between 1 and 3m/s.
Note: Make sure the full-scale flow rate used for the
final planning stage stays within 10m/s in terms
of flow velocity.

Piping Precautions
(1) Design piping so that the flowmeter detector pipe is
always filled with the fluid being measured,
whether the fluid is flowing or not.
(2) The detector has no adjustable piping mechanism.
Install an adjustable short pipe where needed.
(3) The required straight pipe length should comply
with the requirements as follows.
(4) Be sure to ground the flowmeter according to
the flow meter instruction manual.
Required straight pipe length
When using 90-dgree bend, tee, L ≥ 5D
diffuser or fully opened valve
When using other types of L ≥ 10D
valves
Downstream When no valve plate protrudes L ≥ 0
side
into the detector pipe
Upstream
side
L: Required straight pipe length, D: Meter size
Piping materials (to be ordered separately)
Mating flanges:
The flowmeter must be mounted with its detector
pipe connected between the flanges in the pipeline. If
no flanges are used where the flowmeter is to be
mounted, mating flanges are needed.
Adjustable short pipe:
When both the upstream and downstream pipe
sections cannot be adjusted laterally along the pipeline,
an adjustable short pipe may be needed.
Reducers:
When the flowmeter with its Meter size smaller than
that of the pipeline should be installed, reducers are
needed on both ends of the flowmeter detector.
Reducers with pipe extensions:
Reducers with adjustable piping mechanism.
Gasket :
Gasket is needed for piping. In the case of the
detector with grounding ring and Teflon lining,
additional gasket is needed between grounding ring
and lining face.
12
About establishment environment
Do not store or install the flowmeter :
• Where there is direct sunlight.
• Where excessive vibration or mechanical shock
occurs.
• Where high temperature or high humidity
conditions exist.
• Where corrosive atmospheres exist.
• Places that can be submerged under water.
• Where there is a sloped floor. To put the flowmeter
temporarily on the floor, place it carefully with
something, such as a block, to support it so that the
flowmeter will not topple over.
In areas like the following, there may be the case that
infrared switches do not function correctly. (If these
are unavoidable, use an appropriate cover.)
(1) Where unit (operation panel) is exposed to direct
sunlight, reflection of light onto window pane and
diffused light reflection.
(2) Where smoke and steam may occur.
(3) Where exposed to direct snow, ice or mud.

Notes:
1. Exciting cable is a 3-wire chloroprene sheathed cable. For a nominal cross-sectional area of 1.25 mm², the overall diameter will be
12 mm (15/32 inch): for 2 mm², 13 mm(1/2 inch).
2. Signal cable is a 2-wire shielded chloroprene sheathed cable with a nominal cross-sectional area of 0.75 mm² and an overall diameter
of 12 mm (15/32 inch).
3.Relation between exciting cable length and its nominal cross-sectional area and overall diameter is as follows.
